There is no other concealer for me. I am in my forties and am often presenting in front of people after long nights of preparation. This is so natural looking, NO creasing, lasts all day, easy to apply with a finger. Medium and sufficient coverage for dark undereyes and blemishes. I like the pump bottle bc it keeps the product from drying out so it lasts forever - a little goes such a long way. I get nc42 a shade slightly lighter than my C6 studio fix powder foundation. Perfect. Originally posted on www.maccosmetics.co.uk
